GilsoFlex Bitumen/gilsonite Roof Sealer and Paint combined in one product

Developed for New Zealand outdoor conditions

Roof Sealer, oil/water based emulsion roof sealer/paint, ideally suited for sealing and painting of exposed roofs and steel structures,

Biosymph Chemical Products was founded in 2011 and is a 100% New Zealand owned and operated company.

GilsoFlex is a New Zealand manufactured dense black Bituminous/Gilsonite co-polymer, oil/water based emulsion roof sealer and paint ideally suited for sealing and painting of exposed roofs and steel structures, developed primarily for New Zealand outdoor conditions.

Beginning with a very good idea, a load of passion and a great work ethic, GilsoFlex became a reality.

The management and team at Biosymph are proud to provide their top quality products direct to your doorstep.

We know you will find our products as fantastic as we do.

The Biosymph founder holds extensive knowledge in polymer chemistry and chemical engineering. Our products are developed specifically, but not exclusively, for the farming community in New Zealand.

Worldwide research on the practices and products available before GilsoFlex were carried out to find suitable products, but without success.

We felt the only alternative was to develop products ourselves to render the specifications and results that we and our clients desire.

Suitable for sealing and painting of exposed roofs and steel structures.

GilsoFlex is a New Zealand manufactured dense black Bituminous/Gilsonite co-polymer, water emulsion based sealer / paint.

This outstanding product is ideally suited for sealing and painting of exposed roofs and steel structures.

It has been developed primarily for New Zealand outdoor conditions.

Because of its disinfecting effect, it will retard the growth of moss or lichen.

The roof requires one coat only and 10 Litres will cover approximately 30 to 50 Square Metres, depending on the roof surface. Therefore, 1 Litre will cover approximately 3 to 5 Square Metres.

GilsoFlex is intended for surface application by brushing, rolling or spraying. For application by spraying, we supply a suitable thinner.

A re-coat may be required after a 5-8 year period.

The colour is a deep matte black when fully cured. We do however recommend a top coat of our ClimoPlate over the GilsoFlex, in a lighter colour to keep temperatures down.

Pierre van Vuuren

Holding a degree in Polymer Chemistry and Chemical Engineering, Pierre van Vuuren, the founder of Biosymph Ltd., embraced the opportunity to first develop the BitPost Timber Stain and Preserver product line, followed by additional products along the way.

MAF held concerns about the use of Creosote, which led Pierre to conduct extensive research and development to create a safer version of the Creosote product, while still offering the same all-important benefits.

Along with the fantastic Bitpost Timber Stain and Preserver product and the GilsoFlex Roof Sealer and Paint, Biosymph offers great customer service, leading to equally happy clientele.

This business has experienced enormous growth since its beginnings in 2011.

Not only have the public of New Zealand embraced these products, Biosymph is also now exporting to the Australian market.

The products are developed specifically, but not exclusively, for the farming community in New Zealand.

The range of Bitpost Timber Stain and Preserver products is receiving amazing feedback. BitPost repels wasps and red mites, kills lichen and stops horses chewing on fence posts.

The product is easily applied with a roller or brush for post and rail fences and is also available in a refillable 5 litre knapsack sprayer.

Similarly, GilsoFlex Roof Paint and Sealer has been widely applied and sought after by kiwis. This solves the common issue of leaky roofs due to age in an environmentally-friendly and easily-applicable manner.

GILSOFLEX 10 LITRE
April 30, 2016

After searching for a suitable product for a loooooong time, we found GilsoFlex. We ordered 20 litres to test if it would solve our roofing problem and found the product to be excellent, so we ordered some more. Dealing with BioSymph was seamless...they have an excellent Web site, great products and a very good sales team...I highly recommend this company.

BEST WATERPROOFING PRODUCT I HAVE USED
November 8, 2016

This product is better than any of the others on the market. I have used this in a number of situations now and have found it to be the best at waterproofing existing and new roofing materials. It covers flat roof materials where others fail. "Not" being water based is in my opinion its main advantage !

GOOD STUFF
September 8, 2018

Great price - slapped it on the roof and it has fixed 90% of leaks in our 2nd hand iron roof. Thick stuff took a bit to paint on but easy to use and works which is a bonus ! Quick postage, and the tin it came in seals well too.
